Answer:

The length of arc AB is 120 centimeters.

Explanation:

Given information: O is the center of circle and radius of the circle is 4 centimeters. It is given that
$x=30^(\circ)$ .

Length of arc is

$l=2\pi r((\theta)/(360))=r\theta$

Since the radius of circle is 4 and
$x=30^(\circ)$ , therefore

AB=4* 30=120

Therefore the length of arc AB is 120 centimeters.
